New luminescent glasses and prospects of using them in solar energy

Abstract

This paper presents a comparative analysis of the luminescence and absorption of glasses with molecular clusters of silver and selenium and nanocrystals of copper chloride and cadmium sulfide from the viewpoint of spectral down-conversion of short-wavelength solar radiation into the spectral interval of the maximum efficiency of the photoelectric converter of a solar cell. It is shown that UV and violet radiation can be efficiently converted into the 450-700-nm spectral region by appropriately choosing the luminescence centers in glass, and this promises to reduce the number of stages in a solar cell.

Formation of luminescent optical waveguides in silicate glass matrix by the ion-exchange technique

“…В работе [9] показано, что использование люминесцентных волокон в качестве чув-ствительных элементов в датчиках искрения позволяет существенно увеличить чувствительность такого датчика. В работе [10] представлены спектральные характеристики люминесцентных стекол для спектраль-ного преобразования солнечного УФ излучения в видимую область спектра.…”

The effect of ions of rare-earth metals on the temperature dependence of the luminescence of molecular clusters of silver in oxyfluoride glasses

“…It was shown in that paper that the glasses are characterized by the luminescence of silver MCs in the 420-800-nm wavelength range and temperature quenching of the luminescence in the interval from −170°C to 25°C. Studies of the influence of temperature on the luminescence of MCs of the noble metals are important from a practical viewpoint for the application of the given luminescent materials in photonics devices-for example, in optical radiation detectors, LEDs, and solar cells, 15 for the conversion of optical radiation into other regions of the spectrum, 16 as well as for the creation of luminescent temperature sensors. 3 The goal of this paper is to investigate how temperature in the 20°C-250°C range and ions of the rare-earth metals affect the spectral composition and luminescence intensity of OF glasses containing silver MCs.…”
